STABILIZING FLOAT.

Specification of Letters Patent. Patentgd J an, 31, 1922 Applicationfiled October 27, 1920.' Serial No. 420,033.

To all whom it may concern:

Be it known that I, SIDNEY D. JACOBSON, citizen of the United States,and resident of New York city, in the county of New York and State ofNew York, have invented certain new and useful Improvements inStabilizing Floats, of which the following is a specification. I

My invention relates to a self stabilizing float for use in ships, andsuitable for supporting beds, surgeons operating tables, mounts forguns, or other heavy devices on board ship, for the purpose ofcounteracting to a considerable extent the effect ofthe movement of aship at sea, particularly in rough weather. f

In the drawings:

Fig. 1 shows a vertical section of my invention.

Fig. 2 shows a horizontal section upon the line 2-2 of Fig. 1.

My stabilizer consists in a receptacle 3 preferably a section of ahollow sphere as indicated in the drawings, upon, a pedestal 4, ismounted or connected a platform 5, joined preferably by a universaljoint 6. Beneath the platform is a float 8, preferably an air chamber,secured to the-platform 5 by straps 9. 11 is a liquid seal as of leatheror rubber.

The receptacle 3 is filled with water or other liquid to a level 10,sufficient to keel the platform 5 parallel with the plane of the surfaceof the liquid. 'As the ship pro vided with the above apparatus plungesand rolls the level 10 of the water in the holder tends to remainhorizontal, which has the 1.
